provements in GrainDrills, of which the fol-y lowing is a specification.

Our invention relates to improvements in grain-drills, broadcast-seeders, and other machines which employ hoe orcultivator-teeth attached to drag-bars that are pivoted to the main frame of the machine. Y

One of the obj ects of our invention is to provide mechanism for automatically raising the hoes by the draft of the team, through the medium of a lever which can be locked to the drivingaxle and made to revolve therewith.

Another object of our invention isto so construct the oscillating lifting-lever that the y operator can by means of said lever raise or lowerthedragbars Without the intervention of the power of the team, and atl the same time readily lock said lever in any desired position, so as to hold the hoes in or out of the ground, as occasion may require.

Another object of our invention is tocomy bine the devices for lifting the drag-bars with automatic hoeshifting devices which are ,op-

erated by the power of the team, by means of a gear upon the driving-axle, so that the hoes may be lifted or shifted in unison, or independently of each other, by the draft ofthe team. Y

range these automatic llifting and shifting devices in such relation toeach other that the operator, sitting upon the seatattached to the main frame of the machine,may operate these Y 4o several devices without seriously interfering with his guiding the team and managing the machine vin its working operation in the eld. The preferred form of, constructing and arranging these devices Ywill be fully described in connection with the accompanying drawings, in which- Figure 1 is a top plan view of our improvement attached to the grain-drill.- Fig. 2 is av Another ObjectY of our invention is to ar-Y side elevation of the same with one wheel removed.

vshown in Fig. 3. Fig. 5 is a perspective view rigidly secured to the side rails, a'. VThey are j shown as provided with segmental gearmeshoscillating bar B', for shifting the hoes C2 from one to two ranks in the usual manner.

D represents a crank-arm attached to bar B. D" represents .a pitman pivoted at` one end toarm D and at the other end to arcrankpin on gear-wheel d, which revolves on a shaft mounted on foot-lever d, which is pivoted to a bracket, c, which is rigidly secured to the rear rail, ai, of the main frame.

E represents a rigid arm carrying a clutchlug adapted to engage and stop the motion of gear d.

E represents a spring for forcing gear d into engagement with the clutch-arm E.

The above parts have been fully shown in a previous application of ours filed May 26, 1883.

F represents the oscillating bar ]'ournaled upon the main frame.

F represents crank-arms rigidly connected thereto.

j' represents slotted links pivoted to crankarm F. The drag-bars C pass through the slots in these links f.

G represents springs coiled around said links or standards f, the upper ends of which springs are held in place by means of the fianged eollar g, and the lower ends are supported in a sliding socket-collar g.

e represents pins passing through drag-bars Cto prevent the links or standards f from moving forward of the desired point when the drag-bars C are raised. This socket-collar g holds the spring in proper position, and assists in compressing the spring G when the dragba-rs C are raised by means of obstructions striking the hoes C2. This collar gis provided with a gain-arm, g, having downwardly-projecting lugs or forks which straddle pin e, and are sufficiently far apart to allow the neces sary lateral movement of the pin in the act of raising the hocs. A series of holes may be pierced in the drag-bar to allow of the stems f being adj usted backward or forward of dragbar C, as may be desired.

H represents a driving-gear keyed to the shaft A for shifting the hoes of drill, as before described, when gear d is brought into mesh therewith. Y

H represents a driver-s scat, which is attached to thcstandard h, which is adjustably secured to parallel rails I, which are rigidlyr secured to the main frame of the machine.

L represents aliiting-lever pivoted upon the axle A, and adapted to oscillate freely thereon. lts lower end projects below said axle a sufficient distance to form a lifting-arm, Z, to which is pivoted link K, the forward end of which link is pivoted to the crank-arm J, rigidly scenred tothe outer end of rock-shaft F. As leVerL is moved forward .from the operator, sitting on seat H', the arm Z draws link K and crank-arm J backward, oscillating the rockbar F, and through the medium of crank-arm F and standards or links f elevates the series of drag-bars C C.

It may be desirable in some instances to connect the dragbars C Cto the crank-arm F by means of chains, so as to allow the hoes C to be lifted independently and raised freely to pass over obstacles, and when so connected they can be operated by lever L, either with or without the power of the team, in the same manner as when spring drag-bars are employed, except that the hoes C cannot be locked in the ground by means of said lever,

of claims herein. It is also obvious that a single oscillating or sliding shifting-bar, B, might be employed, in lieu of bars here shown, for shifting the position of the hoes, and such a modifica-tion would not affect the features of invention herein shown and described.

In order to lift the hoes by means of the draft of the team, the following instrumentalities are employed in connection with the lever L, oscillating upon the axle A.

M represents a ratchet-wheel hinged upon the axle A between the ground-wheel and the side rails, a a, and in close proximity with lever L.

m represents a pawl or dog pivoted to lever N represents a connecting-rod, one end of which is pivoted to the dog m and the other to a lever, N, which is in turn pivoted to the lever L. NVhen lever N is turned forward from the operator, dog m is brought into engagement with one of the teeth of ratchet M, when lever L is locked to axle A, and moves with it in the same direction as if pushed forward by the operator, thereby raising the hoes out of the ground in the same manner. In order to automatically lock the lever from the axle A', a trip, O, is provided, which is rigidly secured to the side rail, c', above the ratchet M, and a lip or lug, n, upon the inner face of the end of dog m, so as the dog travels forward with the lifting-lever L the lip a will strike the trip O, when lever L is moved to a vertical position, or nearly so, and throws the dog out of contact with the tooth of ratchet M, releasing the lever L, which drops back into position, as shown in Fig. 2. It is sometimes desired, however, to lock the hoes out of the ground and maintain lever Lin aforward position. This can be accomplished by the following means:

P represents a segmental notched bar secured to the frame O, and upon the inside of said lever L, vertically above segment P, a lock-bolt is secured and operated by means of connected rod Qland hand-lever R, pivoted upon lever L, in convenient reach of the hand of the operator. It is sometimes desirable to hold the lock-bolt p out of contact with the notches in the segment P. For this purpose lock-lever N is made with a projection forward of its pivot-point, so that said projection will engage in a notch, s, cut in the shank of lever R1, as shown in Fig. 10, which represents the bolt p withdrawn and lever L free to oscillate. Fig. 9 represents lever L locked to the segment l), in which condition the dragbars C C and the hoes C are rigidly held in 7o and when thus used they embody' the features I of our invention herein set forth as far as they relate to the elevating and depressing of said drag-bars, as specied in the rst three clauses IOC IIO

. (Il,I F i i r 257,779 o Y a position by the lock-lever L. When it is desired to raise the hoes by the draft of the team, lock-bolt p should be held out of engagement with the segment P, which may be done by 5 the hand of the operator, yas well asby the locking devices above described. .'I represents an adjustable stop, of U shape, bolted to segment P, for sustaining thevlever L in its'A backward position. t,

It is obvious that the lock-lever and the device for operating it or locking it to the shaft might be variously modified without chang` ing the features of invention herein set forth. We do not wish to limit ourselves to the specific devices herein set forth; but

What we doy claim as our invention is` l. In a grain-drill, a lifting-lever oscillating upona driving-axle, in combination with f link and crank devices connecting said lever .2o to the oscillating b ar journaled upon the main frame, to which the drag-bars are connected `in such manner that the hoes may be raised or lowered by the oscillation of the lifting-lever, substantially as herein set forth.

2. In a grain-drill having a lifting-lever oscillating upon a driving-axle, and adapted to raise and lower the hoes by link and crank connection to the oscillating bar `]`ournaled on the main frame, in combination with the 3o ratchet-and-pawl devices for locking the lifting-lever to the axle,'substantially as herein set forth.

3. In combination with a lifting-lever, L, oscillating upon a driving-axle, and the means for locking it thereto, an automatic trip arranged upon the main frame and adapted to automatically disengage the locking devices as the lever is moving forward with the axle,

substantially as herein set forth.

4. In combination with the lifting-lever L, oscillating upon the main axle, and having locking devices for connecting the lever to the axle, a bolt-lock attached tothe free end of the lifting-lever, whereby it'may be-'locked in any desired xed position for holding the hoes in or out of the ground, substantially as herein set forth.

5. In combination with the lifting-lever L,

journaled upon the drivingaxle, and lock devices R Q, the secondary lock-lever N', adapted to hold the lock-rodp from engagement withv the segment P, substantially as herein set forth'. Y f

6.
